We've seen Michelle Pfeiffer sing, we've seen her slink around Gotham City, and we've seen her as a drug lord's trophy wife, but now we'll get to see her as a mafia badass.

From "Dangerous Liaisons" to "Dangerous Minds," the Oscar-winning actress gets dangerous yet again in this week's "The Family" alongside Robert De Niro. Pfeiffer's Maggie Blake may look like a sweet little blonde lady, but don't judge a mob boss's wife by her cover -- she'll blow up your convenience store if you make fun of her French.
